Compare protein fragments, count amino acids, and use the information to explore common ancestry. The resource mentions a student worksheet, however, a separate printable worksheet is not provided. The exercises are written into the...

When you get to the heart of the matter, you learn a lot about an organism by studying its circulatory system! A perfect resource for a zoology or anatomy class, the simulation gives users a peek inside a variety of vertebrates to...

What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...

Pupils learn how to control food spoilage by adjusting the food's pH. They see that one of the most dangerous bacteria can grow in food if people don't handle and store food properly. Using knowledge of the bacteria's preferred pH,...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Biology buffs simulate how genetic markers are passed among populations in order to understand how these markers can help anthropologists map human migration. A couple of volunteers leave the room while you walk the remaining learners...

High schoolers discuss the contributions of different organisms to our world. In this biology lesson, students research countries with limited food supply. They create an improvement plan for a fictitious country assigned to them.

High schoolers compare the features of gorilla to humans. In this biology instructional activity, students simulate adaptation using materials found in the classroom. They explain what exaptation means.
